Paper Abstract

DALSA and Philips Digital Video Systems have developed a high performance pinned-photo-diode CCD linescan sensor for scanning of motion picture film. This application requires a sensor with performance optimized for a high dynamic range optical input, with high speed operation. The sensor is named the IL-P2-2048. It is based on the existing DALSA IL- P1-2048 linescan sensor design with a number of significant changes--the full well has been increased to in excess of 300,000 electrons, with a maximum video swing of more than 1000 mV with two bi-directional outputs operating at > 21 MHz video rate. Of importance is the introduction of pinned- photo diode pixels (10 X 10 micron pitch) which possess extremely low fixed pattern noise, low pixel-response non- uniformity, and low image lag. The sensor also has pixel select gates to enable the user to select the full resolution or a reduced number of pixels for use in different imaging formats; the pixel selection is nevertheless dynamic and can be user selectable. The output circuitry has excellent linearity from a few mV to the full signal swing of 1000 mV. In this paper the authors present the design and test results of the sensor.
